But if you look closer, there are one hour intervals between each reply to the post. If we were the same account, then the reply to each post would be closer than just an hour. Why would a single person wait that long to reply to their own post? Plus, the time between account creation is 30 days.

And not all of us are that insane as many of us lack the time to do such a thing. But I won't try to prove anything to make a point any further.
